About Kalman

A Precision CNC Manufacturer in Silicon Valley

Company History and Founder Alan Kalman

Kalman manufacturing, founded by Alan Kalman, specializes in manufacturing specialty, high tolerance parts. Alan developed a passion for machining early in life and has maintained that passion over 35 years while building a business that started in his home, and has since grown to a full scale operation providing high tolerance CNC machined parts for some of the most demanding applications. Alan’s early work in CNC shops taught him both the value of quality, and also the importance of the parts he was making. Today, some of the parts made at Kalman serve in applications like medical robotic assisted surgery devices. We understand that in many cases our parts actually have lives that depend on them, and we bring that understanding to every project we take on. Kalman ensures that all of its employees share a similar passion for their work.
